. To all whom it' may comm STATES- rA'rE Be it known that L'WILLIAM F.BEAsLnY,

a citizenof the United States, and resident of Plymouth, in the countyof lVashington and State of NorthCarolina, have invented certain new anduseful Improvements in Vehicle-Tires, of which the following is aspecification. I

It has been my object to produce as a sub etitute for a pneumatic tire asimple and efficient tire construction which will have all p of theresiliency which is now required of pneumatic tires and [which will bemuch more durable and much cheaper to use.

vAffurther object is to make a tire which can be easily andquicklyapplied to any ordinary wheel which can be easily and guigklyfi' epairedif a part is broken or infat gored. 1 a

l.he.novel features of the invention will bgjzappare'nt fromthefollowing description "eirinconnection with the drawings.

1 :Inthe drawings: Figure 1 is a cross sec- 7 y tion through the rim. ofa wheel having one form of my invention applied thereto; Fig. 2visafsimilar view showing a'slightly modifled construction; Fi 3 1s asimilar view sliowingianother modification; Fig. 4 is a cross section ofa modified construction hav- 3.0

another modification of my invention; Fig.

7 is aside view of a wheel showing how all forms of my tirebasemay beapplied thereto in sections.

Considering now the specific construction shown in Fig. 1, 1 representsthe spokes of an ordinary wheel such as is used on automobiles orsimilar vehicles and 2 represents the wooden rim on which is mounted theordinary clencher rim 3 which has heretofore been used 'to receive thepneumatic tire. In

the clench'er rim I provide a base 4 which is preferably made of woodand which ha's'a contracted lower portion 5 which fits within theclencher rim. The base 4. is made circular in form so as to fitaroundthe rimof the.

wheel and is preferably made in sections i 1. Sp ccific aticn ofELettersEaten til I:

"Hr y t; I. ted Ja'n.'28,-1913.a Application filed June 1, 1e1'1gser1a1'nd: ceases? w!"- "iiim Baton longitudinally sothat it canbe'easily. 'ap'-" plied'to the rim, and those sections 'arefsecured in.place or secured to ether in any suitable way. On the base 4 mountresilient material 5 which will stand compression and which will formwith theupper layer 6 the tread of the tire. I prefer to use as theparticles of old rubber cemented together as set forth in a companionapplication filed by me No. 634,360 June 20, 1911, but it will beunderstood that the tread portion of the tire resting on the base 4, maybe madeof any suitable resilient'material. Radial members or plungers 7of rigid material pass through the base 4 and-through the tread portionof the tire having 'fiattened bearing heads 8 resting on the tread.These radial members are preferably in the form of bolts as shown, andat their inner ends they enter cylindriat this point and is held inposit-ion by a nut 11 so as to limit the outward movement of the bolt.It will be observed 'that by this construction the tread is fastened inplace by means of the bolt and that the resilient tread supports thebolt by means of the head 8. Within the socket 9 I placeresilientsupporting means for the bolt resting on the rim 3, in thisparticular instance t e resilient support being shown in the form of acoiled spring 12. In this construction it will be understood that theweight of the vehicle is supported by the bolts 7 which bolts are inturn resiliently supported both by the tread portions, 5, '6, and thespring 12.

base 4 the friction may 'causeheat, and if desired, the bolt may besurrounded by a collar 13 of asbestos or other heat resisting means.

It will be understood that the number of bolts or supporting 'members 7will depend upon the character of the vehicle on which the tire is usedand that a sufficient number will be employed to give the proper supportversely of the rim as shown in Fig, 6. Since the bolts carry the weightof the vehicle 'tl ere will be, little wear on the resilient OFFICE.

material 5 a rubber composition made from ca] sockets 9 bored in thelower side of the base 4, and a washer 10 is placed on the bolt v Sincethe bolts slide in the bearing in the tothe vehicle. In some forms itwill be nec- I essary to use a number of bolts i h I tread, theprincipal wear being that due to the pressure of the head 8, but this isrelieved by the spring 12.

In Fig. 2 the construction is similar to that described in connectionwith Fig.1 except that the support for the inner ends of the radialmembers or bolts 7 are in this instancein the form of rubber balls 14.The construction shown in Fig. 3 .is the same'except that the support isin this instance in the form of a resilient member 15 bellshaped incross section.

In Figs. 4 and 5 I have shown an arrangement in which I make use of twobolts in line across'the tire, passing through resilient tread sections25, 26, and I cover these sections with the casing 27 of canvas, rawhideor suitable material, the bolts passing. through the casing as well asthe tread. In the form shown in these figures the wheel rim 2 isprovided with a metal rim 16' in place of the clencher rim abovedescribed, this rim 16 being U-shaped in cross section and the rigidbase sections 17 fitting ivithin the U-rim against its base and closeagainst the side flanges. The sections 17 are preferably made of woodsegmental in shape" placed end to end around the circumference, so as tomake up a complete circle. The bolts 24 pass transversely through thesections and through the side flanges so as to removably hold thesections in place- The radial plungers 18 pass through openings in y ofthe plungers resting on the casing.

the sections 17 and are supported at their lower end by the-springs 19,which springs are guided and supported by the side walls of the openingsin the sect-ions17. The plungers-pass through the layers of elasticmaterial 25, 26, on the base of the sections 17 going over astone orobstruction, but only that portion of the tire which strikes it. Thebolts are limited intheir outward movement by the washers 10 and theyare supported not only by the springs within the rigid base but also bythe resilient tread. When, the sections of my tire are used-with-theclencher rim the ends of the sections may be clamped or secured togetherby any suitable means and it will thus be seen that my tire is adapt' edfor use as an emergency tire on any ordi-' nary automobile and is alsoadapted for use as the permanent tire on the same machine."

- for, said plungers.

Stra-ps 28 maybe passed around thesection as shown in Fig. :5 for thepurpose of strengthening it and holding the parts in It will beunderstood that the sections 17 shown in Fig.7 may be made in accordancewith any one of the specific forfns illustrated in the other figures,the base member being made in sections shown as constituting a quarterofthe circumference so that they may be easily and quickly put in placeand if one section is injured a new section may be substituted withouttaking down the en tire wheel.

In this particular form it will be observed that the sections are heldin place in the U rim by means of the bolts passing through them.

Havingthus described my invention what I claim as new and desire tosecure by Letters-Patent .is
